Has anyone tried the hybrid driving techniques on a regular vehicle? Our Concorde (still for sale, LOL) has a continuious MPG reading and we tried some of the techniques with it and had some instant readings of 60 MPG (it usually gets 26 MPG with mixed driving, not bad for a six cylinder, LOL). Anyway, I tried them with my Neon and it dropped the RPM's (does that relate to MPG in any way?). Laurie
